Cometic GM LS Gen-3/4 Small Block V8 .040in MLS Cylinder Head Gasket - 4.035in Bore

Cometic Gasket is known for making well-built engine components, and this Multi-Layer Steel (MLS) head gasket is a prime example. It's designed for GM LS Gen-3/4 small block V8 engines and features a 4.035-inch bore, specifically sized at .040 inches undersize to help you achieve the right compression ratio for your build. This gasket is a solid option for a wide range of vehicles, including models like the Chevrolet Silverado 1500, Cadillac CTS, and Buick LaCrosse.

The key to this gasket's performance is its HP shim technology. This design increases the clamping force around the combustion chamber, which is especially important for open deck blocks like those found in many LS engines. This improved sealability helps prevent leaks and ensures consistent performance under pressure. The outer layers of the gasket are embossed and coated with Viton, a material known for its resistance to heat and oil, further enhancing its sealing capabilities and durability.
